Atmospheric physicist Dr. Murry Salby: Man-made CO2 could only cause warming of 'a few tenths of a degree, if at all'

The man-made share of CO2 in the atmosphere is only a maximum of 30% (0-30%). The remainder is related to temperature changes, natural outgassing from the oceans, and to humidity.

The residence time of CO2 in the atmosphere is only 4-7 years, not hundreds of years as falsely claimed by the IPCC Bern model.

Man-made CO2 emissions increased a whopping 350% faster since 2002, yet the rate of CO2 increase in the atmosphere remained steady at ~2.1 ppm/yr, a "strong indication that anthropogenic emissions can not have a significant or even dominant share."

His conclusion: "Because of the saturation effect in the energy absorption of CO2 molecules with increasing concentration and short residence time, the further increase in temperature could be therefore only at most a few tenths of a degree, if at all. However, the known fossil reserves would be exhausted by then."

Professor Murry Salby, author of two textbooks on physics of the atmosphere, is one of the most renowned atmospheric physicists in the world. His research work began many years ago at the University of Colorado, then Macquarie University in Sydney brought him much scientific and public recognition- up until he made the mistake of publicly calling the climate doctrine into question. From then on he was bullied by many agencies, with baseless accusations marring the funding of his research and was finally "forced to retire" after 56 years of his academic career.

What was the crime of Murry Salby? Well, Salby had methodically by strict and well supported theoretically by such observations and therefore very well argued that almost 80% of the atmospheric concentrations of CO2 are driven by temperature (outgassing) [1]. Not vice versa. The remaining 20% are driven in the main by the moisture. They both work together on the biosphere and the other sources and sinks of the CO2 cycle. Another important aspect of these results is that the residence additionally injected CO2 is about 4-7 years. Although the IPCC expects some 100 or more years, motivated by, because of the long-term effects, including the call for an immediate stop of all anthropogenic CO2 emissions, but the calculations of Salby (and other such as Humlum et al) agree and not the assertion of the IPCC (Fig 2) That the Global Carbon Budget Project comes to completely different results, shows that the research also on this important aspect to the driver of temperature is far from "settled".

After these still very new and important results, Salby turned to in his presentation on how high because of anthropogenically induced share of CO2 is the atmosphere and how it could be determined if necessary. This part of the presentation was very extensive and very theoretical, but always starting from the actual observations. The first of these relates to the fact that the anthropogenic CO2 emissions increased by a whopping 350% faster since 2002 than in previous years. Scoffers would say that this is probably an unintended side effect of the Kyoto Protocol, and a bad omen for the upcoming climate conference in Paris. Yes, and that is the point, the increase in atmospheric CO2 concentration was total over the same period, constant at the previous rate of 2.1 ppm / year.To Salby this is a strong indication that anthropogenic emissions can not have a significant or even dominant share.

Now these two developments he investigated using the known isotopic mixing ratios, and other parameters, and came to the determination that one can only determine the basis of the available data and methods, which currently could be due to the total concentration of the upper limit of CO2 produced by humans.And this limit it to certain complex calculations on the basis by which he led the audience but step by step, with maximum 30%.

His conclusion: Because of the saturation effect in the energy absorption of CO2 molecules with increasing concentration and short residence time, the further increase in temperature could be therefore only at most a few tenths of a degree, if at all. However, the known fossil reserves would be exhausted by then.

Remains to complete and this was his final note that the anthropogenic CO2 emissions almost 1: (Fig. 5) 1 correlate with the development of the world's population.

Unspoken the consequence that no general availability of cheap alternatives to fossil fuels, as you currently may only be provided by nuclear energy, which demanded, reduction of fossil CO2 emissions must lead to a drastic reduction in living standards. And this would have led especially in the poorer countries to a massive increase in the death rate. One or the other listeners felt it perhaps the words of the very famous conservationist and diver Jacques Yves Cousteau recalls, in 1991, was allowed to issue an official UN Brochure . We must "In order to stabilize the planet eliminate 350,000 people per day It's terrible that to say, but just terrible not to say it, " Jacques Cousteau, the UNESCO Courier, November 1991st

[1] For the purists among our readers: Salby determines the correlation coefficient = the net emissions increase of CO2 concentration for the temperature, with almost 0.8 and together with the moisture to 0.93.
